EWS API : In-Place Archive Folder Item Count Issue.

Question

Hi everyone,

I’m working on a C# application using the Exchange Web Services API to retrieve the email count from In-Place Archive folders, including nested ones.

Here’s the code I’m using to get folder Item Count:

Microsoft.Exchange.WebServices.Data.Folder ParentFolder = Folder.Bind(service, FolderName).Result;

Microsoft.Exchange.WebServices.Data.SearchFilter.SearchFilterCollection FilterCollection = new SearchFilter.SearchFilterCollection(LogicalOperator.Or);

FindFoldersResults FoldersResults = ParentFolder.FindFolders(FilterCollection, objFoldView).Result;

Issue: The API response successfully retrieves the folders (no errors or exceptions), but the ItemCount property always returns 0. Even when attempting to retrieve emails directly using the folder ID, the result is still empty.

However, when I check the user's In-Place Archive folder and nested folders manually, emails are present.

Has anyone encountered this issue before, or is there a workaround to retrieve the correct item counts for archive folders?

Thanks,
